CHAP. III. Of the four Elements, their qualities, and mutuall mixtions.
THere are four Elements, and originall grounds of all cor∣poreall things, Fire, Earth, VVater, Aire, of which all elementated inseriour bodies are compounded; not by way of heaping them up together, but by transmutation, and union; and when they are destroyed, they are resolved into Elements. For there is none of the sensible Elements that is pure, but they are more or less mixed, and apt to be changed one into the other: Even as Earth becoming dirty, and being dissolved, becomes Water, and the same being made thick and hard, be∣come Earth again; but being evaporated through heat, passeth into Aire, and that being kindled, passeth into Fire, and this being extinguished, returns back again into Aire, but being cooled again after its burning, becomes Earth, or Stone, or Sulphur, and this is manifested by Lightening: Plato also was of that opinion, that Earth was wholly changeable, and that the rest of the Elements are changed, as into this, so into one ano∣ther successively. But it is the opinion of the subtiller sort of Philosophers, that Earth is not changed, but relented and mix∣ed with other Elements, which do dissolve it, and that it re∣turns back into it self again. Now every one of the Elements hath two specificall qualities, the former whereof it retains as proper to it self, in the other, as a mean, it agrees with that which comes next after it. For Fire is hot and dry, the Earth dry and cold, the VVater cold and moist, the Aire moist and hot. And so after this manner the Elements, according to two contrary qualities, are contrary one to the other, as Fire to VVater, and Earth to Aire. Moreover, the Elements are upon another account opposite one to the other: For some are heavy, as Earth and VVater, and others are light, as Aire and Fire. VVherefore the Stoicks called the former passives, but the latter actives. And yet once again Plato distinguisheth them after another manner, and assigns to every one of them
